Subject Error Configuring Object In Hive Joins
Date Wed, 03 Sep 2014 13:16:20 GMT
Hi all,

I have two hive tables pointing to the same location(folder) when i join
these tables hive fails in map-reduce with the error

java.lang.RuntimeException: Error in configuring object
	at org.apache.hadoop.util.ReflectionUtils.setJobConf(
	at org.apache.hadoop.util.ReflectionUtils.setConf(
	at org.apache.hadoop.util.ReflectionUtils.newInstance(
	at org.apache.hadoop.mapred.MapTask.runOldMapper(
	at org.apache.hadoop.mapred.Child$
	at Method)
	at org.apache.hadoop.mapred.Child.main(
Caused by: java.lang.reflect.InvocationTargetException

	at sun.reflect.DelegatingMethodAccessorImpl.invoke(

	at org.apache.hadoop.util.ReflectionUtils.setJobConf(
	... 9 more

Any idea why this would happen ?
